Cannot read AssociationView using Arduino Client C example

Hi Mikko,

I am using the Arduino Client C example on a Landis Gyr E650, so SN. I successfully connected to the meter using IEC62056-21 Mode E on the public client (0x10) without authetication. However I cannot read the association view. What am I doing wrong?

In com_readAllObjects I added:
ret = com_getAssociationView();
if(ret != DLMS_ERROR_CODE_OK) {
GXTRACE_INT(PSTR("com_getAssociationView failed"), ret);
return ret;
}
GXTRACE_INT(PSTR("com_getAssociationView SUCCEEDED"), ret);
after the connection was made, so after ret = com_initializeConnection();

I also added code to show the request and response in readDLMSPacket(). This gives:
